Computing and analyzing the melting capacity of a single screw extruder, enables the melting section of the screw to be designed around its melting capacity. As a result, Dual Spiral Systems barrier screws assure that the geometry of the screw matches the melting behavior of the polymer (balanced feed screw design).

Our screw designs are tested using the latest screw design software to enable us to optimize their design to process a wide variety of resins. Our high performance barrier screw design also involves an experimental analysis.

Process Improvements

The balanced melting section concept involves matching the geometry of the feed screw to the the melting behaviour of the polymer.
It allows processors to take advantage of various process improvements. The main advantages include lower pressures along the axis screw, higher throughput rates, lower melt temperatures, and more stable extruder operation. Combined with several standard features we offer a high quality screw designed to outperform typical "high performance" feed screws.
